help
Enables performance measurements. Requires ADSP_MW interface. Each created component
can have its performance checked by measuring execution time of copy function.
Performance records are stored in the limited number of slots in Memory Window 3,
so only a certain number (PERFORMANCE_DATA_ENTRIES_COUNT) of components can be measured.
